DESCRIPTION
The ADS1201 is a precision, 130dB dynamic range,
delta-sigma (
Σ
) modulator operating from a single
+5V supply. The differential inputs are ideal for direct
connection to transducers or low level signals. With
the appropriate digital filter and modulator rate, the
device can be used to achieve 24-bit analog-to-digital
(A/D) conversion with no missing codes. Effective
resolution of 20 bits can be maintained with a digital
filter bandwidth of 1kHz at a modulator rate of 320kHz.
The ADS1201 is designed for use in high resolution
measurement applications including smart transmit-
ters, industrial process control, weigh scales, chroma-
tography, and portable instrumentation. It is available
in a 16-lead SOIC package.
